The anatomical neck divides the head of the humerus from the greater and lesser tubercles of the humerus. It gives attachment to the capsular ligament of the shoulder joint except at the upper inferior-medial aspects.
[3] During abduction, the greater tubercle of the humerus comes in contact with the upper margin of the glenoid cavity, which limits maximum abduction. By rotating the humerus laterally, this contact is delayed because the greater tubercle is pulled back so that the bicipital groove faces the coracoacromial ligament. This slightly slackens the ...
The greater tubercle of the humerus is the outward part the upper end of that bone, adjacent to the large rounded prominence of the humerus head. It provides attachment points for the supraspinatus, infraspinatus, and teres minor muscles, three of the four muscles of the rotator cuff, a muscle group that stabilizes the shoulder joint.
At the midshaft of the humerus, the radial nerve travels from the posterior to the anterior aspect of the bone in the spiral groove. A fracture of the humerus in this region can result in radial nerve injury. The ulnar nerve lies at the distal end of the humerus near the elbow. When struck, it can cause a distinct tingling sensation, and ...
It forms two bands [3]: 908 - an anterior one and a posterior one - that insert into the lesser and greater tubercles of the humerus, respectively. [ 4 ] The two bands of the CCL blend with the joint capsule; [ 3 ] : 908 the ligament is intimately united with the capsule by its posterior and inferior border, but its anterior and superior border ...
The glenoid fossa of the scapula or the glenoid cavity is a bone part of the shoulder.The word glenoid is pronounced / ˈ ɡ l iː n ɔɪ d / or / ˈ ɡ l ɛ n ɔɪ d / (both are common) and is from Greek: gléne, "socket", reflecting the shoulder joint's ball-and-socket form. [1]
[3] Less frequently, the anterior part is oblique too, but in the opposite direction of the posterior side. Consequently, during full elbow flexion, the hand tends to rest outside the shoulder. Very rarely, the anterior part is oblique in the opposite direction, resulting in the hand's resting on the chest during flexion. [3]
In human anatomy, the deltoid tuberosity is a rough, triangular [1] area on the antero lateral (front-side) surface of the middle of the humerus. [2] It is a site of attachment of deltoid muscle . [ 2 ]
